Figure 6. Sketch of how to mount a Hall sensor on a stator tooth.

The reflective tape should be mounted over pole number one and the optical sensor should be mounted
in the same position as the Hall sensors, for example upstream.

Figure 7. If the space permits, mount the sensor at an angle relative to the axis.
The sensor is preferably mounted at approximately 20 degrees angle to the horizontal plane, for vertical
axis machines, to avoid reflections from the metal of the shaft.
